how to use foreach

// In the case of swiftui's foreach
// Make sure to import swiftui first as foreach is not native

let names = ["ken","ben"]

ForEach(names) { name in
	Text(name)
}

// this loops through the names, and creates a text view for each name
// so it is something like

Text("ken")
Text("ben")
